[0032] Specifically, the worm gear 16 on the rotating shaft 15 is the output part of the entire transmission system. Driven by the worm 13, the worm gear 16 rotates at high speed, providing powerful power for the equipment. The design of the worm gear 16 fully considers the mechanical principles, so that it can remain stable when running at high speed, reducing the failure rate. In addition, this device is also equipped with a connecting rod 17, which connects the rotating shaft 15 and the clamping plate 18. Driven by the rotating shaft 15, the connecting rod 17 can rotate at a certain angle. This design makes the device more flexible during operation. Finally, the clamping plate 18 slides on the outer wall of the storage box 1 to realize the function of position adjustment and fixation of multiple circuit boards. This design makes the position adjustment of the circuit boards more precise and ensures the stability of the equipment during operation. In short, this device drives the worm 13 and the worm gear 16 on the rotating shaft 15 through the motor 12 for efficient transmission, and then realizes the position adjustment and fixation of multiple circuit boards through the connecting rod 17 and the clamping plate 18.

[0033] Reference Figure 4-5 The moving assembly includes a support frame 2 and a top plate 3, the outer wall of the support frame 2 is fixedly connected to the outer wall of the storage box 1, and the lower surface of the top plate 3 is fixedly connected to the upper surface of the support frame 2; the interior of the top plate 3 is fixedly connected with a slide bar 5, and the outer wall of the slide bar 5 is slidably connected with a slide block 4; the outer wall of the slide block 4 is slidably connected to the inner wall of the top plate 3; the outer wall of the slide block 4 is fixedly connected to a cylinder 6, and the output end of the cylinder 6 is fixedly connected to a connecting plate 7; the inner wall of the connecting plate 7 is fixedly connected to an electric telescopic rod 8, and the output end of the electric telescopic rod 8 is fixedly connected to a slide block 2 9; the outer wall of the slide block 2 9 is slidably connected to the inner wall of the connecting plate 7, and the outer wall of the slide block 2 9 is fixedly connected to a limiting block 10; the outer wall of the limiting block 10 is slidably connected to the inner wall of the connecting plate 7, and the outer wall of the slide block 2 9 is fixedly connected to a suction cup 11;

[0034] Specifically, the slide bar 5 acts as a driving device to drive the slider 1 4 and the cylinder 6 to move under the top plate 3. This process realizes the basic movement of the equipment and lays the foundation for the subsequent transportation link. Next, the cylinder 6 drives the connecting plate 7 to move up and down. This step is to realize the movement of the connecting plate 7 by air pressure drive, thereby providing power for the subsequent component transportation. In this process, the connecting plate 7 plays a connecting role and transmits the movement to the next link. Later, the electric telescopic rod 8 in the connecting plate 7 drives the slider 2 9 and the suction cup 11 under the slider 2 9 to move. This step is to drive the slider 2 9 by the extension and contraction of the electric telescopic rod 8.

The limit block 10 can limit the position of the slider 29 to ensure its safety during the movement. This design reflects the humanized characteristics of the equipment and effectively protects the safety of the operator. Finally, the suction cup 11 drives the circuit board to move, thereby achieving the effect of transporting the circuit board. This process realizes efficient transportation on the production line and greatly improves production efficiency.

[0035] Working principle: When a fully automatic PCB circuit board stacking device is needed, the slider 1 4 and the cylinder 6 are driven to move under the top plate 3 through the slide bar 5, and then the connecting plate 7 is driven to move up and down through the cylinder 6. At the same time, the electric telescopic rod 8 in the connecting plate 7 drives the slider 2 9 and the suction cup 11 under the slider 2 9 to move. At the same time, the position of the slider 2 9 is limited by the limit block 10 to prevent the slider 2 9 from falling off during movement. At the same time, the circuit board is driven to move by the suction cup 11, so as to achieve the effect of transporting the circuit board, and then the motor 12 drives the worm 13 to rotate, and the worm 13 drives the worm wheel 16 on the rotating shaft 15 to operate. The connecting rod 17 is driven to rotate through the rotating shaft 15, and the splint 18 is driven to slide on the outer wall of the storage box 1 through the connecting rod 17, so as to achieve the effect of adjusting the position of multiple circuit boards and fixing the circuit boards.
